I would have done dd if=/dev/zero of=/dev/thecard to force reallocation of bad sectors like I would do on a hard drive but I was afraid that would cause every flash block to be read-modify-written multiple times. I wish we could get direct access to the flash on SD cards like we can do with the NOR/NAND flash to bypass the FTL and use a file system designed for flash. -Phil ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
QI kernel parameters
Hi all, I have a hard time with an SD card that will give errors whne running fsck, even right after an fresh mke2fs. So i am trying to slowdown the glamo, but that does not seem to work with QI acording to [1] i should work for nand in the same way as it does for sd card partitions. But that doesn't seem to be the case. Any other idea on how to supply kernel parameters while booting from NAND?

I needed to change the kernel command line and I found that it was easy to do by changing Qi's source code. Qi is very small so it's not daunting to modify and compiles in to time. All you need is a working toolchain. - git clone git://git.openmoko.org/git/qi.git - find the function append_device_specific_cmdline_gta02 in src/cpu/s3c2442/gta02.c You can just add something like cmdline += strlen(strcpy(cmdline, youroption=yourvalue)); - make - Use dfu-util to flash the result onto the Freerunner. -Phil ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: QI kernel parameters
Hi, Notice, that if your distro-specific qi already has some kernel params changed in source or have some additional patches, you have to use distro-specific qi source as base. You may attempt to cat /proc/cmdline to check that. Alternatively just use u-boot ;) Gennady В Вск, 02/01/2011 в 12:14 -0500, Phil Vandry пишет: On Sun, Jan 02, 2011 at 05:43:36PM +0100, Ed Kapitein wrote: I have a hard time with an SD card that will give errors whne running fsck, even right after an fresh mke2fs.

Re: QI kernel parameters
Hi Phil, Thanks for the tip, it seems like a hassle to recompile qi for setting the glamo clock speed. Anyway, i tried it, and i end up with: neo qi # make mkdir -p image ld: cannot open linker script file src/cpu//qi.lds: No such file or directory make: *** [image/qi--master_c38b062a609f1442.udfu] Error 1 I am building on the FR, so no toolchain there. Did you manage to get your SD card to work? if so how? Also in my case the error follows the SD card, another card (class 6) works just fine, but the new (class 4) is buggy.
